Description
In order to cope with the high luminosity phase conditions at the LHC experiments, the development of detectors with enhanced time resolution and radiation hardness is required. TimeSPOT, an INFN-funded project, has developed 3D-trench silicon pixel sensors able to achieve a very good time resolution for minimum ionizing particles. In 2019, these sensors were tested for the first time on a high-energy charged-particle beam at the Paul Scherrer Institut (PSI) and a time resolution of 20 ps was measured. In order to perform accurate time resolution measurements in our laboratory, a beam test like setup using a $^{90}Sr$ beta emitter was built. The results obtained are in agreement with PSI beam test measurements, implying that such a setup is, at least for sensor time characterization, a valid alternative to high-energy charged-particles beam tests. This setup, together with the characterization of a TimeSPOT 3D pixel sensor, will be presented at the conference.
